阅读说明：本技术 用于心脏辅助系统的泵单元的进给管线、心脏辅助系统和用于生产用于心脏辅助系统的泵单元的进给管线的方法 (Feed line for a pump unit of a heart assist system, heart assist system and method for producing a feed line for a pump unit of a heart assist system ) 是由 英戈·斯托兹 法比安·艾伯格 彼得·瓦瑟曼 于 2019-07-19 设计创作，主要内容包括：本发明涉及用于心脏辅助系统(100)的泵单元(110)的进给管线(105)。进给管线(105)被体现为将流体流引导到心脏辅助系统(100)的泵单元(110)。进给管线(105)包括：进给头部分(130),进给头部分具有至少一个引入开口(140),以用于将流体流引入到进给管线(105)中；以及具有内表面轮廓的轮廓部分(135)。轮廓部分(135)邻近进给头部分(130)设置。轮廓部分(135)的在第一位置处的内直径大于在第二位置处的内直径。为了减小内直径,内表面轮廓在第二位置处是倒圆的。(The invention relates to a feed line (105) for a pump unit (110) of a heart assist system (100). The feed line (105) is embodied as a pump unit (110) directing a fluid flow to the heart assist system (100). The feed line (105) comprises: a feed head portion (130) having at least one introduction opening (140) for introducing a fluid stream into the feed line (105); and a contoured portion (135) having an inner surface contour. The contoured portion (135) is disposed adjacent the feed head portion (130). The inner diameter of the profile portion (135) at the first location is greater than the inner diameter at the second location. To reduce the inner diameter, the inner surface profile is rounded at the second location.)
